We'll leave it there for today.

It's been an emotional few hours on stage 13.

Chris Froome looks unstoppable on his way to a third Tour de France title.

But we have been reminded today that, on occasions, sport can bring people together, when it feels, at times, society can be so fractured.

Join us for stage 14 tomorrow.

Chris Froome may have extended his lead in the yellow jersey, but his thoughts have been very much with the victims and their families in Nice.

Froome lives in Monaco, which is close to Nice.

"This is definitely a time for people to stand together. It definitely puts things into perspective for us. I'm happy with how it went but everyone's thoughts are with the people in Nice. It's a special place for me, close to where I'm based, and I can't imagine what everyone is going through."

In respect to those who have lost their lives in Nice, there are no podium presentations today.

Instead, Chris Froome, stage winner Tom Dumoulin, green jersey wearer Peter Sagan, king of the mountains leader Thomas de Gendt and young rider leader Adam Yates stand on stage for a minute's silence.

They all lay their bouquets of flowers on the podium - a symbolic gesture - and then walk off stage to a respectful round of applause.

An emotional scene.

Team Sky's Geraint Thomas reflects on the attack in Nice on ITV4: "It's so sad and terrible. Things like that shouldn't happen. It's the world we live in today and it puts bike racing into perspective. My thoughts go out to everyone."

Stage winner Tom Dumoulin: "On one side I'm a very happy man but on the other side it's a very sad day. I woke up to the terrible news from Nice and there was a question whether we should race. It was a just decision in the end to race. We cannot let terrorists decide our lives in society. It's terrible what happened and it shadows the day a lot."

Here's the top 10 in the race for the yellow jersey.

Adam Yates is down to third. Nairo Quintana is pretty much three minutes behind Chris Froome.

If today was anything to go by, Bauke Mollema is now the biggest threat to Chris Froome's crown.

Only time will tell if he spent everything on the time trial today.

It turns out my maths was spot on - Mollema moves up to second, 1min 47secs behind Froome.

My very, very quick maths tells me Chris Froome has extended his lead in the yellow jersey to 1min 47secs over Bauke Mollema, who moves into second place.

Chris Froome is making it look easy. He finishes in second place, 1min 13secs behind stage winner Tom Dumoulin.

Adam Yates - second overall overnight - finishes seven seconds quicker than Nairo Quintana.

Now. Nairo Quintana, what have you got?

Here he comes to the finish... provisional 18th with a time of 53mins 23secs.

Chris Froome engages with the climb to the finish line and looks completely in control. I don't envy anyone who has to try and close the gap to the yellow jersey man after today.

Mobile video has emerged of Nairo Quintana grabbing on to a motorbike through the mess left by the crash with Porte, Froome and Mollema yesterday.

I'm sure the Colombian would argue he was trying to safely negotiate through the crowds - but some riders are not happy.

Bauke Mollema looks like the only general contender to get a shift on so far today as he crosses the finish in fifth place - 1min 53secs behind leader Tom Dumoulin.

I feel it will still be about limiting how much time Chris Froome wins though.

Chris Froome now comes through the third checkpoint. He's going quick.

It's nowhere near Tom Dumoulin, but nobody has been so far.

Froome is the second quickest at that point on the course, though - 48secs behind the stage leader.

But, importantly, it's almost two minutes quicker than Quintana's pace.

And here's Adam Yates - overall second - going past the same point as Quintana. He's two places higher and 14secs quicker than the Colombian. Could he gain time?

Nairo Quintana squeezes his nose as he crosses the 28km point. That's a rare waver from the Colombian's usual granite stare.

The Movistar man is down in 23rd - 2mins 30secs off the lead pace.

If you consider Chris Froome was 30secs off the pace at the previous checkpoint - Quintana could lose a chunk of time.

Bauke Mollema is the first general classification contender to put in a notable time on the third and final time check - he's in provisional eighth - quickest of the GC guys to go through that point so far.
